Get a taste of Scroll development with these code snippets:

Configuring Hardhat

...
//
// Select the network you want to deploy to here:
//
const defaultNetwork = "scrollSepolia";
...
module.exports = {
...
  networks: {
...
          scrollSepolia: {
            url: "https://sepolia-rpc.scroll.io/",
            accounts: {
              mnemonic: mnemonic(),
            },
          },
  }
...
}

Creating a simple fungible token

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract MyToken is ERC20 {
    constructor(uint256 initialSupply) ERC20("MyToken", "MTK") {
        _mint(msg.sender, initialSupply);
    }
}

These examples showcase:

1. How to configure Hardhat.
2. A simple ERC20 fungible token contract that can be deployed on Scroll.
